The application reads (scans) selected sections of leads calculates wave amplitudes and intervals and makes ECG analysis.
ECG analysis is proposed to be performed sequentially on 12 leads or immediately read 3 ECG leads 4 times to analyze all 12 leads.

Attention.
The recording speed should be 25 mm/sec.
Drawings of ECG leads must be horizontal and do not touch each other.
The phone camera must have autofocus.
DISCLAIMER:
The results may be erroneous. The app shows a new ECG optical recognition technology bat does not replace medical analysis.
The reliability of the results of the study depends on many factors: light ECG recording quality technical characteristics of the smartphone and etc.
